To mil whom t may concern:

Be it known that I, SIDNEY JAMES IVIL- Lmu's, a subject of the IInitedKingdom ot Great Britain and Ireland, residing at No.

83 vAbingdon Villas, Kensington, in the county of London, England, haveinvented new and useful Improvements in or Relating to IgnitionApparatus for Ilse with Internal-Combustion Engines. of which thefollowing is a specification.

This invention relates to ignition apparatus for use with internalcombustion engines and is particularly applicable tor use,

. with motor cars.

The object of the invention is to avoid the use ot a magneto-generator;to increase the efficiency ot' the motor-starter; and to reduce the costot mamitacture.

According to my invention I use a non` trembler coil with a contactbreaker, a yhigh tension distributer and two condensers, to take theplace, of the magneto-generator and in order to enable an internalcombustion engine to be started I use a trembler in parallelv with thenon-trembler induction coil. Between the earth lines ot the nontremblerlcoil and the trembler I introduce ,an additional earth line. tor thepurpose ot t cou'ipleiing a circuit at starting through the two primarywindings ol the trembler and non-trembler coil. in spite ot' the t'actthat the contact-breaker may be open. so that iminediately a stud. orbutton. on the additional earth line. is depressed and the circuitcompleted, sparking takes place in the cylinder and continues until thestud is rcleased, when the trembler is cut out ot circuit. which iscompleted through the nontren'iblercoil and the contact breaker operatedi'roin the valve shal't.

In the accomjmnying drawings is illustrated a method oi' carrying theinvention into practical eii'ect.

is the battery. or other source of electric energy. It' is the lowtension or primary coil l'or operating the trembler coil. being thenon-trembler. I) is the condenser used in conjunction with the tremblercoil Il. D is the, condenser used in conjunction with they non-tremblercoil (l. Fisthe trembler and l*V the bridge for same, operating inconjunction with the coil Il and the non-treinbler coil (l. I is thecontact breaker operated from 'the valve shaft, or other suitable partot the engine. A dist ributer It, operated in asimilar manner to the.contact breaker I. connect-s the source of electric energy with thesparking plugs, each in the order in which it is desired the sparkshould take place. L is the push button to enable the additional earthline M to be brought into operation when it is desired to start theengine.

The modus operandi is as follows lVhen the button L is depressed thecurrent from the batter-yA passes through the primary windings of thecoil B and the trembler mechanism F. It", causing the current to Howthrough both the trembler and non-trembler coils C although the Contactbreaker I. which is ope ated trom the valve shaft, may be open. One endof the primary winding ot' each coil is connected in parallel at It" tothe bridge piece. The additional earth line M having the push button Lis connected across the earth of the coil B and non-trembler coils Cwhen the push button is depressed.

It' it be required to start the engine, although the Contact breakercircuits be open, by depressing the push button Il the circuit isconnected to earth through the additional earth lino M, enabling thecurrent to pass from the coil I3 and non-trembler coil C to earth,thereby inducing the required current in the secondary windings of thenon-trembler coil (l. The button Il may then be released and thenon-trembler coil C will come into operation through the contact breakerI, enabling thc correct sparking to take place in the cylinders. l

lly the use ot apparatus as above the cost ot' construction isconsiderably reduced; the starting ot the engine may be effected withoutthe necessity ot' using the ordinary starting gear; and the eiliciencyof the ignition device is increased, augmented induction arising in thenon-trembler coil C as a consequence ot the additional iron in the samefield produced by the core in the, primary coil Ii.

An ignition apparatus for internal combustion engines,comprising a source ot' electric energy, a trembler. a primary coil inparallol with a non-trembler coil. a high tension distributer, twocmidensers one connected to the primary coil and one to the non-tremblercoil, a contact breaker connected to the valve shaft. in combinationwith an additional earth lint` between the earth lines ol the two coils,and a depression titl Bti:
